제목 Regeneration of Bone Tissue using Silk Fibroin-PGA Hybrid Scaffolds Prepared by Electrospinning and 3D Printing Techniques
초록 Tissue engineering aims regeneration of defected biological tissues and organs by combining cells, scaffolds, and growth factors. We developed patient-customizable guided bone regeneration (GBR)/guided tissue regeneration (GTR) hybrid scaffolds prepared by electrospinning and 3D printing techniques. Poly(glycolic acid) (PGA) scaffolds were prepared by a 3D printer. The topography of silk fibroin nanofibers and PGA scaffolds was observed by SEM. Cell seeding efficiency and proliferation of osteoblasts on a PGA scaffold were analyzed by MTT assay. Rabbit calvarial defect model was used for animal test. Bone tissue regeneration were analyzed by Masson Trichrome staining and micro-CT. Silk fibroin nanofiber-PGA hybrid scaffold groups showed significant regeneration of bone compared to control groups. The silk fibroin nanofiber-PGA scaffold construct will be an efficient approach for regeneration of bone defects.
